Non-degradative histone ubiquitylation plays a myriad of well-defined roles in the regulation gene expression and choreographing DNA damage repair pathways. In contrast, contributions degradative on genomic processes has remained elusive. Recently, APC/C been shown to ubiquitylate histones regulate pluripotent cells, but molecular mechanism is unclear. Here we show that despite directly binding nucleosome through subunit APC3, unable nucleosomal histones. extranucleosomal H2A/H2B H3/H4...
The mechanism by which HIV-1 reverse transcriptase (HIV-RT) discriminates between the correct and incorrect nucleotide is not clearly understood. Chemically modified nucleotides containing 1-aminonaphthalene-5-sulfonate (ANS) attached to their γ-phosphate were synthesized used probe selection this error prone polymerase. Primer extension reactions provide direct evidence that polymerase able incorporate gamma-modified nucleotides. Forward mutation assays reveal a 6-fold reduction in...
Iron is a critical component of metabolic homeostasis, but consumption dietary iron has increased dramatically in the last 30 years, corresponding with rise disease. While link between metabolism and health well established, extent to which contributes disease risk unexplored. Further, it unknown how interacts genetic background modify risk.
Oxidized soluble guanylate cyclase (sGC) heme iron (Fe 3+ ) is desensitized to nitric oxide (NO) and attenuates cGMP production needed for downstream activation of PKG-dependent signaling vasodilation. While reactive oxygen species drive oxidation sGC iron, the basic mechanism(s) governing recycling its NO-sensitive, reduced state 2+ ), are unknown. Here we report cytochrome b5 reductase 3 (Cyb5R3), also known as methemoglobin reductase, a novel regulator in vascular smooth muscle cells...
